We witness in our day-to-day life the frictional force taking place in moving bodies which are in interaction. This is called kinetic friction. Rolling friction and sliding friction falls under this topic. The Retarding force observed as kinetic friction in the two moving aircraft as they touch with each other. The kinetic friction is expressed as Where, Fk is Force of […]

Formula of Wave Speed The Wave speed formula which involves wavelength and frequency is given by: v = f λ Where, v is the velocity of the wave f is the frequency of the wave λ is the wavelength Related Topic : What is LibreOffice? LibreOffice Impress Features ? […]

As we understand, the air resistance decreases the speed of a plane while moving. Air resistance is a force that is caused due to air when an object moves through it. This force acts in the opposite direction to a body passing through the air. […]

According to Hooke’s law, the force applied to stretch the spring is directly proportional to the amount of stretch. Force required to stretch the spring is directly proportional to its displacement. It is given as F =kx Wherein, k = spring constant x = displacement […]

The magnetic field generated by the currents is usually termed as the magnetic field B.B is sometimes called the magnetic flux density or magnetic induction. The magnetic field is measured in Tesla. But when these fields produced are passing through the magnetic material, which has […]

Specific Gravity gives information about the weight and density of the object. It can be calculated by comparing the weight, mass and density of the given object with water of the same amount at 40C. Specific Gravity Formula is or or Specific gravity is a unitless […]

Heat Flux Heat flux is the amount of heat transferred per unit area per unit time to or from a surface. Basically, it is a derived quantity since it involves the principle of two quantities viz. the amount of heat transfer per unit time and […]

Measurements are used to measure something. It is the estimation of ratios of quantity. It is made by comparing a quantity with a standard unit. They are used to find the size, length or amount of something. Measurement Formulas are used to find the distance, […]

Everybody in the universe pulls every other body with a force that is directly proportional to their mass-produced and inversely proportional to the distance square between them. The Gravitational force formula is given by Where,G is universal gravitational constant,m1 and m2 are mass of bodiesr is the radius between the two masses Related Topic : Chemistry Formulas List Maths Formulas List What is LibreOffice? LibreOffice Impress Features ? LibreOffice Impress CCC Questions and Answer […]

Potential Energy Formula The formula for gravitational potential energy is given below. PE = mgh Where, PE is the potential energy of the object in Joules, J m is the mass of the object in kg g is the acceleration due to gravity in ms-2 […]

Impulse A car is travelling at full speed. It crashes into the barrier, because of the negligence of the driver. Here the huge force is applied on the wall by the car in a very little time interval which we term as an impulse. Impulse […]

Heat Rate The heat rate is defined as the total amount of energy required to produce one kilowatt-hour (kWh) of electricity by an electric generator or power plant. The formula of heat rate is Rh = Ws × c × ΔT Where, Rh is heat […]

Formula of Elastic Collision The Elastic Collision formula of momentum is given Where, m1 is the mass of 1st body m2 is the mass of 2nd body u1 is the initial velocity of 1st body u2 is the initial velocity of the second body v1 […]

The amplitude of a wave is the maximum displacement of the particle of the medium from its equilibrium position. It is represented by A. The Amplitude formula can be written as where, y is the displacement of the wave in meters A is the amplitude […]
